false alarm prevention circuitry
False alarm prevention circuitry bypasses any zone that triggers the system more than three times with-
in a one-hour period. For a full description refer to the Owner's Guide.
power-up
power-up ensures that the when the system is powered up it will return to the same state it was in when
power is disconnected. For a full description of power-up refer to the Owner's Guide.
troubleshooting
Starter kill doesn’t work.
➤
Is the correct starter wire being interrupted? If the car starts when the starter kill relay is completely
disconnected, the wrong starter wire has been cut and interrupted.
➤
YELLOW wire is not connected to true ignition. It is connected to an accessory circuit.
Shock sensor doesn’t trigger the alarm.
➤
Has the false alarm prevention circuitry been triggered? If so, you will hear five chirps when
disarming. To check this, turn the ignition key on and off to clear the false alarm from memory,
and then retest the shock sensor. For a detailed description, see Owner’s Guide.
Door input does not immediately trigger full alarm. Instead, I hear chirps for the first three
seconds.
➤
That’s how the progressive two-stage door input works! This is the instant response feature of this
system. Even if the door is closed immediately, the system provides an instant trigger by chirping,
and the progressing to a constant siren.
Closing the door triggers the system, but opening the door does not.
➤
Have you correctly identified the type of door switch system? This happens often when the wrong
door input has been used.
System will not passively arm until it is remotely armed and then disarmed.
➤
Are the door inputs connected? Is a blue wire connected to the door trigger wire in the vehicle?
Either the green H1/5 or the violet H1/7 should be used instead.
Door input does not respond with the progressive trigger, but with immediate full alarm.
➤
What zone does the LED indicate? If the LED indicates that the impact sensor caused the trigger,

tion circuitry by turning on the ignition after every third system trigger.
